Unit definition:
One Unit of L-glutamic-oxaloacetic transaminase activity is defined as the amount of enzyme required to convert one μmole of α-ketoglutarate to L-glutamate per minute in the presence of NADH at pH 8.5 and 25oC.
Specificity:
Catalyzes the reversible transfer of an α-amino group between aspartate and glutamate.
Applications:
Applications in diagnostics and analytical methods in the food and feeds, fermentation, beverages and wine industries.
